TWIN FALLS, Idaho -

An 87-year-old man accused of fatally shooting a woman in Twin Falls has been deemed unfit to stand trial.
   
The Times-News reports that on Monday a judge ruled that Paul Robert Welch is not competent to stand trial because he can't help his defense. Welch has been ordered to undergo treatment to restore his competency.
   
Welch is accused of killing 81-year-old Barbara Sue Chitwood. Chitwood was found dead from gunshots to her head at the home she shared with Welch on Aug. 21, 2015.
   
Welch appeared in court Monday for just the second time since February, as a series of errors and miscommunications had delayed his mental competency evaluation.
